The background is, I'm working on an 802.1x project, I need to find the printer, the quickest solution in this case is to look in the ARP cache of the router/switch on site.

The irritant is that in the email the MAC is in EUI format, but routers/switches are in Cisco's. To Further irritate, Cisco ISE and ACS use EUI format so if someone sends you a MAC address from a switch or their windows machine then you need to convert it, I've spent a lot of time replacing dots and dashes :D

Today, I realised that I could use Apple's Automator to grab text from somewhere... I could then parse it through my python scripts and have the results in my clip board... ready for pasting!
